Problems solved by technology

It can be seen that after the introduction of E-DCH, the admission control is more complicated than the admission control of R99 pure DCH, and the admission control cannot be performed simply by predicting the interference increment. It is necessary to comprehensively consider the target interference threshold, real-time interference, DCH and E -DCH service distribution, service throughput, etc. for acceptance judgment
In the prior art and currently published patent documents, there is no technology related to E-DCH admission control

Embodiment Construction

[0032] Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail:

[0033] see figure 1 As shown, it is a general flowchart of WCDMA admission control in the prior art; the general flow includes the following steps:

[0034] Step 101, node Node B 11 measures uplink interference and sends a measurement report to RNC 12, wherein the measured uplink interference is I_total;

[0035] Step 102, the user equipment UE 13 initiates an access request for accessing the service to the RNC 12;

[0036] Step 103, RNC 12 calculates the interference increment ΔI, and judges that ΔI+I_total

[0037] Step 104, the RNC 12 permits the user equipment UE 13 to access the service; and

[0038] Step 105, RNC 12 rejects user equipment UE 13 to access services.

[0039] see figure 2 As shown, it is a flow chart of E-DCH admission control in the present invention, and...

Abstract

The invention is used in WCDMA system. The system comprises radio network controller, Node B and subscriber equipment connected to it. The method comprises: 1) setting a threshold and measuring the service throughput and uplink interference; 2) the radio network controller sorts the service into a GBR type service and a non-GBR type service; 3) making the throughput decision and interference decision for the GBR service, and only making user's number decision for the non-GBR service in order to realize the uplink enhanced channel reception control.

Description

technical field [0001] The invention relates to the field of WCDMA communication, in particular to an admission control method of an uplink enhanced channel in a WCDMA communication system. Background technique [0002] The capacity and coverage of the WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) communication system in the uplink direction are limited by interference. For the received signal of a certain user, the base station receiver regards the uplink signals of all other users as interference to this user. In order to overcome the near-far effect, the WCDMA system adopts closed-loop power control technology, so that the signal power of all users of a certain service received by the base station receiver is basically the same. When a new user accesses, the interference to the existing users in the system is increased. In order to maintain the call quality, under the effect of closed-loop power control, all users increase the tra...
